| Abstract: |
| It mainly introduces the
implementation technology and the physical simulation of WAW?1 power System security
Emergency Control Equipment.The equipment is of multi-CPU distributed and hierarchic
system. It uses common memory to realize high-speed communication, solves the technical
problems of in-phase sampling and state switchover of same data window calculation and
synchronous calculation in the multi-CPU system by both software and hardware. The
physical simulation results show that the equipment can follow the run-state change of
power plant feeders, alarm correctly when line overload occurs; forecast transient
stability correctly when fault occurs and put in off-load measures to prevent system
instability. The equipment can check-up synchronization loss and start up disconnection
when power system dynamic instability occurs, which meets the expected control demand. |
